Stutterbump Training Wheels were invented by Paul Bacon in 1999 when he saw a gap in the market that needed to be filled. They were the worlds first sprung training wheel and have been going strong ever since. Made by hand from Australian products in Rushworth Victoria, every set is made and put together, packed and shipped from our small business. Recently a copycat of Stutterbump Training Wheels has been released on the market. They are an inferior product that is not hand made but bares the name Stutterbump. Do not be fooled into buying this nasty rip-off of our wonderful product. It is a stolen design and they have stolen the name Stutterbump. We trade under Stutterbump Training Wheels. Our product is far superior and we stand by our name. Stutterbump Training Wheels. Happy Riding Everyone!!
